Anthurium plant named &#39;ANTHDOTFAN&#39;

ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHDOTFAN’ particularly distinguished by having red, cordate and very durable spathes that retain the original color for a very long period of time, brown and cordate, durable leaves, pinkish cataphylls, reddish brown peduncles, rich flowering continuously throughout the year and a plant height of 30 cm to 35 cm, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHDOTFAN’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium,botanically known as Anthurium andreanum L., and hereinafter referred toby the variety name ‘ANTHDOTFAN’. The new variety originated from ahybridization made in September 2006 in Bleiswijk, The Netherlands. Thefemale parent was a dark red Anthurium pot plant designated ‘9842-01’(unpatented), and the male parent was a red Anthurium plant designated‘9632-01’ (unpatented).

A single plant was selected in November 2008 and has been asexuallyreproduced repeatedly by tissue culture in Bleiswijk, The Netherlandsover a seven-year period. The present invention has been found to retainits distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in theEuropean Union on Nov. 18, 2013. ‘ANTHDOTFAN’ has not been made publiclyavailable or sold anywhere in the world more than one year prior to thefiling of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Bleiswijk, The Netherlands:

-   -   1) Red, cordate spathe;    -   2) White spadix with yellow tip;    -   3) Brown cordate leaves;    -   4) Reddish-brown peduncle; and    -   5) Pinkish cataphyll.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘ANTHDOTFAN’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 40-week oldplants which were planted from tissue culture in 14-centimeter pots andgrown in a glass greenhouse between 19° C. and 24° C. Observations weremade in August 2015. Color readings were taken under 5000 lux naturallight in the greenhouse. Color references are primarily to The R.H.S.Colour Chart of The Royal Horticultural Society of London (R.H.S.)(2015).
